                                                                 @Nullable

                                                                 @Nullable org.moe.natj.general.ptr.Ptr<NSError> outError)
        appendSampleBuffer:decodeTime:presentationTime:error: Appends sample data to a media file and adds sample references for the added data to a track's media sample tables. If the sample buffer carries sample data, the sample data is written to the container specified by the track property mediaDataStorage if non-nil, or else by the movie property defaultMediaDataStorage if non-nil, and sample references will be appended to the track's media. If both media data storage properties are nil, the method will fail and return NO. If the sample buffer carries sample references only, sample data will not be written and sample references to the samples in their original container will be appended to the track's media as necessary. Note regarding sample timing: in a track's media, the first sample's decode timestamp must always be zero. For an audio track, each sample buffer's duration is used as the sample decode duration. For other track types, difference between a sample's decode timestamp and the following sample's decode timestamp is used as the first sample's decode duration, so as to preserve the relative timing. Note that this method does not modify the track's sourceTimeMappings but only appends sample references and sample data to the track's media. To make the new samples appear in the track's timeline, invoke -insertMediaTimeRange:intoTimeRange:. You can retrieve the mediaPresentationTimeRange property before and after appending a sequence of samples, using CMTimeRangeGetEnd on each to calculate the media TimeRange for -insertMediaTimeRange:intoTimeRange:. It's safe for multiple threads to call this method on different tracks at once. This method throws an exception for any of the following reasons: - the sample buffer's media type does not match the track's media type - the sample buffer contains image buffers (must contain encoded video) - the sample buffer contains caption groups (must contain encoded media data) API-Since: 13.0
        Parameters:
        sampleBuffer - The CMSampleBuffer to be appended; this may be obtained from an instance of AVAssetReader.
        outDecodeTime - A pointer to a CMTime structure to receive the decode time in the media of the first sample appended from the sample buffer. Pass NULL if you do not need this information.
        outPresentationTime - A pointer to a CMTime structure to receive the presentation time in the media of the first sample appended from the sample buffer. Pass NULL if you do not need this information.
        outError - If the appending fails, describes the nature of the failure. For example, if the device containing the track's media data storage is full, AVErrorDiskFull is returned.
        Returns:
        A BOOL value indicating the success of the operation.

If NO, sample data will not be written and sample references to the samples in their original container will be added as necessary. Note that in this case, this method will fail if the original samples are fragmented.

You should note that a format description can have extensions of type kCMFormatDescriptionExtension_VerbatimSampleDescription and kCMFormatDescriptionExtension_VerbatimISOSampleEntry; if you modify a copy of a format description, you should delete those extensions from the copy or your changes might be ignored. This method throws an exception if the media type of the new format description does not match the media type of the receiver. API-Since: 13.0
        Parameters:
        formatDescription - A CMFormatDescription occurring in the array returned by the -formatDescriptions method.

      • sampleReferenceBaseURL

        @Nullable
public @Nullable NSURL sampleReferenceBaseURL()
        [@property] sampleReferenceBaseURL For file types that support writing sample references, such as QuickTime Movie files, specifies the base URL that sample references are relative to; may be nil. If the value of this property can be resolved as an absolute URL, the sample locations written to the file when appending sample references to this track will be relative to this URL. The URL must point to a location contained by any common parent directory of the locations that will be referenced. For example, setting the sampleReferenceBaseURL property to "file:///Users/johnappleseed/Movies/" and appending sample buffers that refer to "file:///Users/johnappleseed/Movies/data/movie1.mov" will cause the sample reference "data/movie1.mov" to be written to the movie file. If the value of the property cannot be resolved as an absolute URL or if it points to a location that is not contained by any common parent directory of the locations that will be referenced, the location will be written unmodified. The default value is nil, which means that the location will be written unmodified.

        public void setPreferredMediaChunkAlignment​(long value)
        [@property] preferredMediaChunkAlignment For file types that support media chunk alignment, the boundary for media chunk alignment (in bytes). The default value is 0, which means that no padding should be used to achieve chunk alignment. It is an error to set a negative value for chunk alignment.

      • setPreferredMediaChunkDuration

        public void setPreferredMediaChunkDuration​(CMTime value)
        [@property] preferredMediaChunkDuration For file types that support media chunk durations, the maximum duration to be used for each chunk of sample data written to the file. The total duration of the samples in a chunk will be no greater than this preferred chunk duration, or the duration of a single sample if the sample's duration is greater than this preferred chunk duration. The default media chunk duration is 1.0 second. It is an error to set a chunk duration that is negative or non-numeric.

      • setPreferredMediaChunkSize

        public void setPreferredMediaChunkSize​(long value)
        [@property] preferredMediaChunkSize For file types that support media chunk sizes, the maximum size (in bytes) to be used for each chunk of sample data written to the file. The total size of the samples in a chunk will be no larger than this preferred chunk size, or the size of a single sample if the sample is larger than this preferred chunk size. The default media chunk size is 1024 * 1024 bytes. It is an error to set a negative chunk size.

      • setPreferredTransform

        public void setPreferredTransform​(CGAffineTransform value)
        [@property] preferredTransform A CGAffineTransform indicating the transform specified in the track's storage container as the preferred transformation of the visual media data for display purposes; the value is often but not always CGAffineTransformIdentity.

      • setPreferredVolume

        public void setPreferredVolume​(float value)

      • setSampleReferenceBaseURL

        public void setSampleReferenceBaseURL​(@Nullable
                                      @Nullable NSURL value)
        [@property] sampleReferenceBaseURL For file types that support writing sample references, such as QuickTime Movie files, specifies the base URL that sample references are relative to; may be nil. If the value of this property can be resolved as an absolute URL, the sample locations written to the file when appending sample references to this track will be relative to this URL. The URL must point to a location contained by any common parent directory of the locations that will be referenced. For example, setting the sampleReferenceBaseURL property to "file:///Users/johnappleseed/Movies/" and appending sample buffers that refer to "file:///Users/johnappleseed/Movies/data/movie1.mov" will cause the sample reference "data/movie1.mov" to be written to the movie file. If the value of the property cannot be resolved as an absolute URL or if it points to a location that is not contained by any common parent directory of the locations that will be referenced, the location will be written unmodified. The default value is nil, which means that the location will be written unmodified.

      • setTimescale

        public void setTimescale​(int value)
        [@property] timescale For file types that contain a 'moov' atom, such as QuickTime Movie files, specifies the time scale of the track's media. The default media time scale is 0. This property should be set on a new empty track before any edits are performed on the track.

      • setVersion_static

        public int timescale()
        [@property] timescale For file types that contain a 'moov' atom, such as QuickTime Movie files, specifies the time scale of the track's media. The default media time scale is 0. This property should be set on a new empty track before any edits are performed on the track.
